I've been using a Framework 16 laptop that was originally installed with F40
and updated to F41 (XFCE Spin), without any issues. I just ran into a
hillarious installation issue, posting it here in order to feed the search
engines.
I just received a second Framework 16, so I fed the F41 XFCE spin image to
it. After booting it the keyboard responsiveness was horrible. Typed text
took 5-10 seconds to be echoed back in the terminal, or in Anaconda.
I thought I had a hardware issue, I even took it apart again, and reseated
the keyboard connector, no dice. Still lagging. But when I booted to a grub
prompt, the keyboard was perfectly normal.
I booted back into the live image. Eventually I had a Eureka moment: I have
to keep the mouse moving, constantly, in order for I/O processing to occur.
I can type ahead, then touch the touchpad, and all the buffered input got
echoed back immediately. Some further experimentation I determined that not
only keyboard input, but also some display refreshing gets stuck until I
manually move the mouse.
The kernel that's shipping with the F41 live images is a dud. I ran the
Anaconda installer (constantly twiddling the touchpad to keep everything
moving), then rebooted (the problem remained), then dnf-update-d. After
rebooting into the latest kernel, 6.11.10, everything was working fine.
